Virtual Directory configuration in Exchange Server 2019

December 23rd, 2018 | Posted by admin in Exchange | EXchange 2019

Exchange Server 2019 automatically configures Internet Information Service Virtual Directories related to the Exchange. Clients will connect to these Virtual Directories to access the Services provided by Exchange Servers. This post shows the default configurations of Exchange Server 2019 Virtual Directory.

Internal and External URL, SSL configuration and the Authentication methods are the important parameters related to Virtual Directories, we will see all those configurations in detail.

Below are the Virtual Directory created during the Exchange Server 2019 installation.

I have preferred mail.superhybridcloud.com as the namespace for the all the exchange services and I already changed it. Exchange Certificate installation and configuration are already done.

Auto Discover:

Auto Discover allows the email clients like Outlook to discover the mailbox settings and configure the mailbox automatically without entering the details like server information etc. Service Connection Point object in AD will be referred by Auto Discover to get the User information.

Get-ClientAccessService is command to configure the Internal Url and the Authentication Methods as shown below.

No need to set the Internal / External Url using Set-AutodiscoverVirtualDirectory as it is applicable when using Exchange Server 2010.

MAPI over HTTP:

MAPI over HTTP is the default protocol for Outlook in Exchange Server 2019 and the Exchange 2019 installation warns the MAPIHTTP enablement if it is not enabled. To ensure it is enabled, use Get-OrganizationConfig command.

Set-MapiVirtualDirectory command be used to manage MAPI over HTTP related settings

Exchange Control Panel:

Exchange Control Panel is where an admin can access Exchange Admin Center to manage the Exchange Service. Basic Authentication and FBA are the default Authentication method set on the ECP virtual directory.

Use Set-ECPVirtualDirectory command to manage the ECP virtual directory related settings.

Outlook on the Web (OWA):

OWA virtual directory allows the emails access using Web Browser and we can use Set-OWAVirtualDirectory to configure the OWA virtual directory settings

Active Sync:

Mobile Device clients that support Exchange Active Sync connects to Active Sync Virtual directory to access the mailbox.

Default configuration will not set any Authentication we can enable basic to allow the clients to access the mailbox using Active Sync protocol.

Set-ActiveSyncVirtualDirectory command allows you to configure the Active Sync related settings.

Offline Address Book (OAB):

Outlook clients using Cached mode requires offline address book to access the address book when it is not connected to exchange.

You can use Set-OABVirtualDirectory command to modify the OAB settings

Exchange Web Service (EWS):

EWS virtual directory supports many features like free busy look up, calendar sharing, mail tips and OOO etc. You can use Set-WebServicesVirtualDirectory command to manage EWS virtual directory settings.

Outlook Anywhere (OA / RPC over HTTP):

MAPI over HTTP is the default protocol for MAPI clients having mailbox in Exchange Server 2019 but it still supports Exchange for legacy clients that does not support MAPI over HTTP.

Set-OutlookAnywhere command can be used to manage Outlook Anywhere related settings.
